Clinical application of modern pain sciences for people with bleeding
disorders
Cat Pollard Regional Physiotherapist for
Haemophilia and Complex Pain New Zealand
Pain Prevalence in Haemophilia • HERO study (2014):
– 47% of surveyed adults with all severities of haemophilia reported chronic pain.
– 89% reported pain interfered with their daily lives.
• American study (2017): – 85% of respondents reported experiencing pain over the past 6
months. – Of those with severe haemophilia 88% reported pain and in
mild/moderate haemophilia 79% reported pain.
• European survey (2012): – 6000 people with haemophilia in 22 treatment centres - 35% of adults
and 8% of children reported having ‘chronic’ pain.
Pain most prevalent in people with inhibitors, followed by people receiving on-demand treatment than those on prophylaxis.
Acute Pain
Bleeding related
Injury related – inflammation
Usually short lived
Can usually be fixed
Normally ends
Chronic
Pain Peripheral changes e.g. joint
damage / degeneration
Neural changes – central or peripheral sensitisation
Long lasting, possibly never goes away fully
Not easily fixed
Can be associated with other sensations
Can be emotionally draining and fatiguing.
Acute pain management following a bleed
Step 1: Factor
Step 2:
Step 3: Analgesia (pain relief)
Clotting occurs and healing process follows – reason for the pain goes away.
Biopsychosocial model of health
Bio • Joint health status
• Bleeding phenotype
• Access to factor replacement therapy
• Inhibitors
• Other health issues
Psycho • Self-esteem
• Beliefs and expectations
• Mood – depression, anxiety, stress, fear
• Learning, thinking
• Coping skills
Social • Ability to support family – if work
affected
• Ability to play with children
• Ability to help around the house
• Time away from home (hospital stays)
• Loss of independence
• Impact on work, loss of productivity, loss of income
• Social interactions – ability to enjoy time with family, friends
Pain Management in PWBD
– BIO: Focussing on the periphery * Surgery * Physiotherapy * Orthotics * Exercise * Functional adaptations * Diet and Lifestyle
– PSYCHO: Focussing on the central nervous system
* Relaxation * Acupuncture * Hypnosis * Electrotherapy (TENS) * Mindfulness * Exercise * CBT * Diet and Lifestyle
– SOCIAL: The bigger picture • Education of patient, family, work, school etc. regarding
impact of living with a bleeding disorder, management strategies etc.
• Support networks – haemophilia camps, Haemophilia foundation, social workers, HTC team.
Surgery
Joint replacement (arthroplasty)
Synovectomy Joint fusion (arthrodesis)
Joint debridement Soft tissue release (contractures)
Osteotomy
Physiotherapy
• Joint mobilisations
• Manual treatments
• Exercise
• Electrotherapy
• Acupuncture
• Taping techniques
• Hydrotherapy
• Splinting/ orthotics
Locally influences the tissues, but also stimulates ‘Pain Gate mechanism’
Acupuncture
• Conflicting results for benefits in the literature when treating pain of various conditions.
• 2 published studies exploring it in haemophilia
pain management – both of small sample sizes, but both indicating some benefit in reducing pain.
• Both studies reported that no bleeding or
bruising was experienced by any subjects whether factor replacement therapy was given prior to acupuncture or not.

Exercise and pain the patients perspective…..
“the background [pain] is generally less which definitely helps make day-to-day tasks less of a struggle both physically and mentally”
“I feel that I'm not expending as much mental energy on constantly dealing with physical pain and that then leaves me better able to cope with the acute pain that I experience from day to day”. “Pain is something that I've lived with to varying degrees all of my life and it's not something that I will ever be completely free of...Being physically fitter and more capable has definitely made a very major contribution to my ability to cope with pain and generally feel better about myself and my situation…… primarily because of consistent exercise, I am in one of the best periods of my life to date.”

Hypnosis
• Reports of Rasputin hypnotising Alexis to stop bleeding (Massey, 1975)
• Hypnotherapy reported to reduce bleeding among haemophiliacs during dental surgery (Lucas 1965)
• Self-hypnosis + relaxation + education + support = reduced reliance on factor concentrate to control bleeding (Swirsky-Sacchetti and Margolis, 1986)
• Can be useful in managing needle phobia.
Relaxation
• Winds down nervous system
• Improves descending inhibitory control
• Reduces stress hormones
• Improves mental focus
• Improves coping skills
• Helps with sleep
• Not all pain is related to a bleeding episode
• Chronic pain is more complex than focussing on peripheral tissues.
• There are a number of non-pharmacological approaches which can be utilised or taught to individuals with bleeding disorders.
• A biopsychosocial approach focussing on all elements which contribute to pain experience should be applied.
